That's why I said 666 in a way...Because death can be the work of Satan, so can evil, and evil brings death...Hence the parentheses...666 represents the Beast, not death. The number is representative of Satan.
Also, 777 represents the number of the sacred works of God, 888 is representative of the Christ and 999, representative of God.
It's all interesting stuff.
40 is biblical numerology...It rained for 40 days and 40 nights for example...7 As well? Heh, that's good luck over here. That's just goes to show that it is superstition. I've never heard of 40 either. 3 and/or 4 I think in Japan.
